Soil Water Infiltration Rate
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 2 benchmarks together — the MinimumOnly form drives the primary score, while 1 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
An infiltration rate of less than 40 mm/hr for clayey soils and less than 15 mm/hr for sandy soils indicates severe structural degradation.
Soil water infiltration rate below which essential ecosystem functions are significantly impaired, indicating severe structural degradation.
This benchmark represents the lower critical infiltration rate threshold for sandy soils in tropical and subtropical rainforest production forestry, below which soil structure is severely degraded and ecosystem functions are impaired.
Based on quantitative data from heavily compacted skid trails representing severe mechanical disturbance.
